' 2 Claims The invention relates to improvements in a material for use in musical heads such as banjos and drums, air-motors and air-planes; and the objects of my improvements are: to produce a head of a better grade in elasticity, resonance and tone quality; a material that is water-proof on both sides and not afiected by weather conditions; that does not easily deteriorate by'fungi decay or fermentation, also having both sides dry and smooth to the touch thereby preventing an easy accumulation of dirt, as is the case of heads covered with hides.

I attain these objects by using a finely woven cloth, preferably silk, in combination with chemicals consisting of two formulas.

A silk cloth of the desired shape is fully saturated with a rubber glue or cement from both sides, which has for its solvent a terpene, pe-

troleum benzine, carbon disulphide or ethereal solution, which has no acid or hydroxide effect. The ingredients in this application must agree with the second solution, in solvency, on the out- I am. aware that prior to my invention mi material has been contrived to substitute hide for musical heads that require strength, elasticity and tone quality: I therefore claim such a combination.

I claim: 1. The process of cloth which consists of first impregnating a silk fabric with a solution of rubber in a solvent selected from the group consisting of turpentine,

petroleum benzine, carbon disulfide, and ether, then drying the impregnated fabric, then applyingto one side of the dried fabric a solution consisting of 10 parts by weight of turpentine, 2 parts ether,5 parts alcohol, 5 parts beeswax, and 5 parts of camphor,and finally drying the second coating. 1

2. A silk fabric impregnated with rubber and carrying on one side thereof'a coating consisting of equal amounts of beeswax and camphor.
